摘要: An air supply apparatus of an air lubrication type ship of the present invention includes a turbocharger 10, taking-out means, a pressure-increasing path 41a, a bypass path 51, and path selecting means which selects the pressure-increasing path 41a and the bypass path 51, and the path selecting means selects the pressure-increasing path 41a and/or the bypass path 51 to supply the pressure-increased air and/or the pressurized air and eject the same to the surroundings of the ship's hull. Therefore, even if pressure of pressurized air supplied to the main engine 6 by the turbocharger 10 is varied by output of the main engine 6, and even if draft pressure is varied by a loaded state, pressure of the pressurized air can be increases in accordance with the variations and the pressurized air can be ejected, energy efficiency is high and an energy saving effect can be enhanced.

摘要: Disclosed is a heat energy recovery system including: a heat energy recovery circuit that causes a working medium to circulate by means of a circulation pump to exchange heat with supercharged air from a supercharger via a first heater and exchange heat with steam from an exhaust-gas economizer via a second heater, in order to integrally drive a turbine and a generator; and a controller that performs stop control to stop the circulation pump based on the flow state of the steam in a first steam flow path that causes the steam to flow from the exhaust-gas economizer to a soot blower.

摘要: A heat energy recovery system includes an evaporator, a superheater, an expander, a power recovery device, a condenser, a pump, and a controller. The controller includes: an engine load calculation section; a maximum rotation speed determination section for determining a maximum rotation speed of the pump which is obtained when a pinch temperature reaches a target pinch temperature, based on a relational expression representing a relationship between the engine load and the maximum rotation speed, and an engine load; and a rotation speed regulation section for regulating the rotation speed of the pump in such a way as to allow the degree of superheat of the working medium flowing into the expander to be equal to or greater than a reference value, and to allow the rotation speed to be equal to or less than a maximum rotation speed determined by the maximum rotation speed determination section.

摘要: Provided is a marine propeller that strikes a favorable balance between suppressing cavitation at a blade tip and avoiding stress concentration in a propeller blade. Two inflection points are provided in a rake distribution of a propeller blade (10) of a marine propeller, where a portion from a blade root section (11) to the first inflection point (12) has a backward rake and a portion from the first inflection point (12) to the second inflection point (13) has a forward rake. The portion from the second inflection point (13) to a blade tip (14) has zero rake so as to be orthogonal to the propeller shaft line A-A. The first inflection point (12) is preferably at a position that is 40 to 60% of the propeller radius, and the second inflection point (13) is preferably at a position that is 80 to 95% of the propeller radius.
